Kumveka bwino kwa valve yamkuwa.

Valavu yamkuwa ndi valavu yotetezera yomwe imapangidwa ndi zitsulo zamkuwa zosungira madzi, gasi, hydraulic, etc. Mapangidwe a zida zamkuwa zamkuwa amafotokozedwa kuchokera kuzinthu zinayi: kupanga nkhungu, kusintha kwamagulu azinthu, kusintha mfundo zosankhidwa ndi njira yopangira njira.

Kutulutsa ma valve ndi kuwongolera
(1) Kuponyera mchenga: njira yoyamba yopanga m'mundaMalo Ogulitsa Mabomba Okhazikika Kwambiri Cw617n 1inch Female Ferrule Angle Seat Brass Ball Valve, chifukwa palibe kukakamizidwa kokwanira pakuponyera, ma valve opangidwa ndi ndondomekoyi amatha kukhala ndi mabowo a mchenga, zomwe zimapangitsa kuti pakhale zovuta zambiri zomwe zimayambitsidwa ndi kutayikira kwa mankhwala.

(2) Kuwotcha kotentha: thupi la valve lopangidwa silidzakhala ndi trachoma komanso maonekedwe okongola kwambiri.
Kusintha kwamagulu azinthu

Vavu yachipata chamkuwa: valavu yachipata imatanthawuza valavu yomwe chidutswa chake chotseka (chipata) chimayenda molunjika motsatira njira.Amagwiritsidwa ntchito kwambiri podula sing'anga pa payipi, ndiko kuti, kutsegulidwa kwathunthu kapena kutsekedwa kwathunthu.

Valavu ya mpira wamkuwa: idachokera ku valavu ya pulagi, gawo lake lotsegulira ndi kutseka ndi mpira, womwe umagwiritsidwa ntchito kuzungulira 90 ° mozungulira nsonga ya ndodo kuti akwaniritse cholinga chotsegula ndi kutseka.

Valavu yoyimitsa yamkuwa: imatanthawuza valavu yomwe gawo lake lotsekera (disiki) limayenda pakatikati pa mpando wa valve.Malingana ndi mawonekedwe a kayendedwe ka valve disc, kusintha kwa doko la mpando wa valve kumagwirizana kwambiri ndi maulendo a valve disc.

Copper check valve: Ndi valve yomwe imatsegula ndi kutseka diski ya valve malinga ndi kutuluka kwa sing'anga yokha, ndipo imagwiritsidwa ntchito pofuna kuteteza kubwerera kwapakati.

Kusankha mfundo kusintha

Malinga ndi kusankha kwa ntchito zowongolera, ma valve amitundu yonse ali ndi ntchito zawo.Samalani ntchito zawo zogwirizana posankha.

Malingana ndi momwe ntchito ikugwirira ntchito, zipangizo zamakono za ma valve omwe amagwiritsidwa ntchito nthawi zambiri zimaphatikizapo kupanikizika kwa ntchito, kuthamanga kwakukulu kovomerezeka, kutentha kwa ntchito (kutentha kochepa komanso kutentha kwakukulu) ndi sing'anga (kuwonongeka ndi kuyaka).Posankha, ziyenera kukumbukiridwa kuti magawo omwe ali pamwambawa akugwira ntchito amagwirizana ndi magawo aukadaulo a ma valve.

Sankhani malinga ndi dongosolo la unsembe.Kukonzekera kwa dongosolo la payipi kumaphatikizapo ulusi wa chitoliro, flange, ferrule, kuwotcherera, payipi, ndi zina zotero. Choncho, mapangidwe a valve ayenera kukhala ogwirizana ndi mapangidwe a payipi, ndipo ndondomeko ndi miyeso iyenera kukhala yofanana.

Kukhazikitsa njira kusintha
Valavu yolumikizidwa ndi ulusi wa chitoliro imalumikizidwa ndi ulusi wa chitoliro kumapeto kwa chitoliro.Ulusi wamkati ukhoza kukhala ulusi wa chitoliro cha cylindrical kapena ulusi wa chitoliro, pamene ulusi wakunja uyenera kukhala ulusi wa chitoliro.

Valve yachipata yolumikizidwa ndi ulusi wamkati imalumikizidwa ndi kumapeto kwa chitoliro, ndipo kutalika ndi kukula kwa ulusi wakunja kumapeto kwa chitoliro ziyenera kuyendetsedwa.Pofuna kupewa kusokonekera kwambiri kwa chitoliro kumapeto kwa nkhope yamkati ya ulusi wa chitoliro cha valavu yapamwamba ya chipata, kuchititsa kuti mpando wa valve uwonongeke komanso kusokoneza ntchito yosindikiza.

Malo Ogulitsa Mabomba Okhazikika Kwambiri Cw617n 1inch Female Ferrule Angle Seat Brass Ball ValveMukayika ndi kupukuta valavu yolumikizidwa ndi ulusi wa chitoliro, gawo la hexagonal kapena octagonal kumapeto komweko kwa ulusi lidzaphwanyidwa, ndipo gawo la hexagonal kapena octagonal kumapeto kwa valve silidzagwedezeka, kuti mupewe deformation ya valve.

Flange ya valavu ya flanged ndi flange ya mapeto a chitoliro sikuti imangogwirizana ndi ndondomeko ndi kukula kwake, komanso ndi kuthamanga kwadzina.

Pamene kutayikira kwa tsinde la valve kumapezeka panthawi yoyika ndi kutumiza valavu yoyimitsa ndi valavu yachipata, sungani nati yopondereza ponyamula, ndipo samalani kuti musagwiritse ntchito mphamvu zambiri, popanda kutaya madzi.
